Abstract
A radar method is described herein. In accordance with one embodiment the method includes receiving a plurality of chirp echoes of transmitted radar signals, generating a digital signal based on the plurality of chirp echoes, and calculating a range map based on the digital signal. The range map includes a plurality of values, each value is represented by an amplitude value and a phase value, and each value is associated with one frequency bin of a set of frequency bins and one chirp echo of the plurality of chirp echoes. The method further includes identifying chirp echoes which are affected by interference and determining, for one or more selected frequency bins, corrected phase values based on phase values that are associated with chirp echoes not identified as affected by interference.
